DETACHABLE PLATE FOR CONCEALED MANIFOLDS OF GAS RANGES.

Application filed May 10,

This invention relates to improvements in detachable plate for concealedmanifolds of gas ranges and the present invention has relation to stoveswhich contain a concealed manifold having projecting handles for workingthe gas valves.

The present improvement is for use also in connection with a concealedmanifold having attached gas valves which are also concealed, thehandles for operating the gas valves projecting through the front of therange.

In the manufacture of gas ranges having a concealed manifold andconcealed gas valves, much trouble has been encountered in their use byreason of the necessity of getting access to the concealed elements, forthe purpose of repairing, cleaning, etc.

Heretofore in the use of a concealed manifold, gas valves and theirhousings, there has been no means by which the parts can be detached,adjusted or cleaned, without disconnecting the entire manifold from thestove.

In the use of my present improvement the front of the range in which themanifold, gas valves and their housings are concealed, comprisessubstantially a rectangular frame having its upper horizontal portionlocated 0 above the manifold, gas valves and their housings, and adetachable plate located below the upper portion of the rectangularframe that conceals the manifold, valves and their housings from theoutside of the range.

lln carrying out my present improvement, this detachable plate comprisesa "series of long vertical slots to receive the projecting handles, andalso comprises a series of short vertical slots located between thehandles to permit access by means of a screw driver from the outside tothe usual shutter for regulating the amount of air passing to the burnermanifold.

By means of this detachable plate it is only necessary to remove a screwat each end and slide the plate'downward, causing the handles to movethrough said slots, when access is permitted to the valves and theirhousings from the front of the range, thus not necessitating the removalof the whole manifold as usual, noi' necessitating the removal of an ypart of the range excepting the detachable plate.

The prrsent improvement also relates to an inner shield for themanifold, the valves 1927. Serial No. 190,201[

and their housings, whereby the said parts are wholly concealed from theinside as well as the outside. The principal object in providing thisshield is as a means of protection to the valves, their housings andalso the manifold. This shield serves to protect the valves and theirhousings from the immediate heat of the burners located in the range,whereby they are not subjected to excessive heat that would cause thevalves to tend to freeze or stick, and thereby make them inoperative.The present shield further protects them from the heat by being formedof a double plate having a. filling of asbestos or mineral wool, thusforming a non-conductor for the radiated heat from the burners.

Further improvements in the invention here disclosed will be explainedin the description of the parts.

In the accompanying drawings:

Figure 1 is a perspective view of a gas range showing my presentimprovement applied thereto.

Figure 2 is a. vertical cross section through one of the handle verticalslots.

Figure 3 is a vertical sectional view some what similar to Figure 2,taken at one side of the handle slot and showing a screw driver inposition for adjusting the shutter for regulating the amount of airmixed with the gas.

Figure 4 is a detached front view of the upper portion of therectangular frame showing the detachable plate in position on the frameand the handles projecting through the slots of the said plate.

Figure 5 is a horizontal view of Figure 4; looking from the inner side,and showing the shield in position and its cooperating parts.

Figure 6 is a view looking at the rectangular frame from the inner side,the shield being removed, exposing the manifold, gas valves and theirhousings.

This improvement as stated, is on a gas range, such as shown inFigure 1. In this figure an ordinary conventional range is shown with myimprovement attached thereto, and also used in conjunction with an ovenheat regulator. In this view, 1 indicateswhat is usually referred to asthe open burner construction of the range, though in this instance itstop portion 2 is preferably clo ed, and 3 is the oven and broiler partof the range.

The front portion of my improvement on tively narrow vertical strip, themanifold the conventional range, comprises a rectangular frame 4, thatforms a marginal construction.

In the arrangement here shown, I place the manifold 5 adjacent the upperhorizontal portion 6 of the rectangular frame, and below the manifoldare a series of valve housings 7 that have upwardly extendingcommunications 8 connected with the said manifold. These housings arepreferably conical in shape, as shown and the gas valves (notspecifically shown) are correspondingly so shaped.

It will thus be seen that the manifold is concealed from the front ofthe store by the upper horizontal member 6 of the horizontal frame, andfor the purpose of concealing said housings 7 and their gas valves 7from the outer side of the range, I use an improved detachable plate 9.This plate is provided with vertical elongated slots 10 in which thehandles 11 of the valves oscillate vertically for opening and closingthem; the outer portion 12 of the handles are enlarged.

For the purpose of enclosing the inanifolds, valves and their housingsfrom the inner side of the range, I provide a depending member 13 thathas its end 14 located as shown. This member 13 I term a shield and itextends downward a distance substan tially to the lower portion of thedetachable plate 9. This shield is so shaped as to receive interiorly,an asbestos or mineral wool filling 15, whereby it provides anon-conducting heat member, and thus shields the valve housings andvalves from the direct heat of the burners in the housing 1.

By reference to Figure 2, it will be observed that a horizontal frame 16extends across the front end of the part 1 of the range, and this member16 extends downward as shown at 17. forming a rectangular member that isclamped in a manner to be presently described.

The manifold 5 in this improvement is supported by means of a holder 18.This hold-er 18 (of which there are two) is provided with a curvedportion 19 that [its the inner side of the manifold 5 and extends aroundunder it as shown. while its upper end 20 abuts against the under sideof the member 16 and a screw 21 passes through the member 16 and intothe part 21, thus serving to unite the parts together. The manifold 5 isclamped between vertically arranged members 22. placed between themanifold and the frame 6. and these members 22 are connected with theflange 17 by means of a suitable screw 23. It will be understood, ofcourse, that the members 22 may be omitted and the manifold clampeddirectly between the flange 6 and the holder 18. By provid- 111g members22 that consist of simply a relais held out of contact with the part 6,thus making a circulation of air around it.

It will be understood, of course, that gas nipples 24 communicate withthe valve housings 7 and that these nipples extend inward into a gas andair mixing member or 01121111 her 25, that is connected with a manifold26 that extends inward and is operatively connected with the burner, notshown, located in the housing 1. As is usual, the front end of thismember 25 has an oscillatory shutter member 26 that is held in itsadjustment by means of a screw 27. This member needs to be adjusted toget the proper mixture of air with the gas, and to carry out the idea ofthe present improvement, the detachable plate 9 has its upper edgeprovided with short slots 28 that register with openings 29 in theshield, whereby a screw driver 30 may be passed through said slot andsaid opening and engage the screw 27, thus enabling the shutter to beadjusted from the outside of the range structure.

In order to permit the passage of the nipples 24.- through the shield,the latter is provided with a plurality of openings 31, the openingsbeing located in proper position for their passage.

This shield is held in position by means of screws 32 which pass throughhorizontat slots 33 into the holders 18.

I adapt my present improvement to be used also in connection with a heatregulator 34, by means of which gas is supplied to an oven burner (notshown), and in this event the heat regulator is connected by a suitabletube 35 to a valve having a handle 12' that is connected with themanifold the same as the other valves. This improvement is especiallyadapted for use in connection with the oven heat regulator.

Many ranges are fitted with a lighter. which is not here shown. In theevent of an automatic lighter being used, it passes through a shortvertical slot 28, thereby adapting this improvement for use with thevarious types of stoves. The nipple (not shown) for the automaticlighter (not shown), passes through an opening 36 made in the shield 13.

The plate 9 in the form here shown is made of cast metal, and it may.be-enameled, but I desire it understood that sheet metal may be usedinstead of the cast metal.

It will be observed that the detachable plate is here shown connectedwith the frame 4: by means of screws 4 passing therethrough, and throughlips 5 that extend from the inner edge of the wall 4 of the rectangularframe.

It will be observed from the drawings and the description that incarrying out my improvement I have the frontwall of the housing for theburners, which is referred to as the open part, constructed rectangularin form. I show the rectangular portion large enough to include a dooror other member 37, though that is not essential to the invention sincethe rectangular portion may be made of a size adapted to receive thedetachable plate 9.

Also the valve is so constructed that when the handles 12 are down, theburners are turned off, and below the vertical openings 10 I placetheword Off, and also indicate which one of the burners controls the ovenheat regulator.

By this improvement a concealed manifold, valve housings and valves canbereadily manufactured'and sold, and the same be adapted to be readilyrepaired or cleaned either by the manufacturer, dealer or user, withoutthe necessity of removing the manifold, which is necessary in otherconstructions having a concealed manifold that are known to me.

I have described in considerable detail my present improvement, but Idesire itto be understood that the specific constructions may, in manydetails, be varied so long as they are within a fair scope of theappended claims,
